Anode material for secondary battery, secondary batteries using the same, method for manufacturing anode material for secondary battery and secondary batteries using the same

Abstract

Disclosed are an anode material for a secondary battery, a secondary battery using the same, a manufacturing method of the anode material for a secondary battery and a secondary battery using the same. The present invention provides an anode material for a secondary battery including an anode active material; and a coating material with which a surface of the anode active material is coated using a mixture of a conductive material and a pitch which is a low-crystallinity carbonaceous material, wherein the conductive material in the coating material is included in a content of 0.2% by weight or more of the anode active material and the low-crystallinity carbonaceous material. According to the present invention, the secondary battery having an excellent electrical property may be provided by preventing a charging/discharging efficiency and a charging/discharging capacity of the battery from being deteriorated, and simultaneously improving conductivity of the electrode.
